compiler/nodes

This library provides a series of methods for interacting with the internal representation of nodes.

`builtin`

Native defined at lib/compiler/nodes.lisp:64:1

Get the builtin with the given NAME.

`builtin?`

Native defined at lib/compiler/nodes.lisp:54:1

Determine whether the specified NODE is the given BUILTIN.

Example

> (builtin? (symbol->var `lambda) :lambda)
out = true

`constant?`

Native defined at lib/compiler/nodes.lisp:68:1

Determine whether the specified NODE is a constant.

`(fix-symbol symbol)`

Defined at lib/compiler/nodes.lisp:46:2

Convert the quasi-quoted SYMBOL into a fully resolved one.

`node->val`

Native defined at lib/compiler/nodes.lisp:72:1

Gets the constant value of NODE.

`node-contains-var?`

Native defined at lib/compiler/nodes.lisp:80:1

Determine whether NODE contains a reference to the given VAR.

`node-contains-vars?`

Native defined at lib/compiler/nodes.lisp:84:1

Determine whether NODE contains a reference to any of the given VARS.

VARS must be a struct, mapping variable names to true.

`symbol->var`

Native defined at lib/compiler/nodes.lisp:34:1

Extract the variable from the given SYMBOL.

This will work with quasi-quoted symbols, and those from resolved ASTs. You should not use this on macro arguments as it will not return anything useful.

`traverse-node`

Native defined at lib/compiler/nodes.lisp:20:1

Traverse NODE with VISITOR.

VISITOR should be a function which accepts the current node and the visitor. It should return the replacement node, or the current node if no changes should be made.

`traverse-nodes`

Native defined at lib/compiler/nodes.lisp:28:1

Traverse a list of NODES, starting at IDX, using the specified VISITOR.

See traverse-node for more information about the VISITOR.

`val->node`

Native defined at lib/compiler/nodes.lisp:76:1

Gets the node representation of the constant VALUE.

`var->symbol`

Native defined at lib/compiler/nodes.lisp:42:1

Create a new symbol referencing the given VARIABLE.

`visit-node`

Native defined at lib/compiler/nodes.lisp:6:1

Visit NODE with VISITOR.

VISITOR should be a function which accepts the current node and the visitor. This is called before traversing the child nodes. You can return false to not visit them.

`visit-nodes`

Native defined at lib/compiler/nodes.lisp:14:1

Visit a list of NODES, starting at IDX, using the specified VISITOR.

See visit-node for more information about the VISITOR.
